Building a Golden Dataset and Evaluating Retrieval Quality
Course: RAG Evaluation Level: Beginner to Medium Type: Individual Duration: 5 to 7 days Objective This assignment tests your ability to build the two foundational components of any RAG evaluation workflow: a golden dataset and a retrieval quality report. Without a golden dataset, no evaluation metric has meaning. Without retrieval evaluation, you cannot tell whether failures come from the retrieval stage or the generation stage. By completing this assignment, you will have a

The Part of RAG Nobody Talks About: What Happens Before the LLM Generates an Answer
When people talk about RAG systems, the conversation tends to focus on the same things: which LLM to use, how to write a better prompt, which vector database to choose, how to reduce API latency. Those are real concerns. But there is a quieter layer that gets overlooked almost every time. What happens to your documents before a query is ever asked? The answer to that question determines more about your system quality than almost any other decision. And yet it is the part of R

Why Hybrid Search and Re-Ranking Is the Retrieval Skill Every AI Developer Needs
Most developers building with LLMs focus on the model. They tune prompts, swap models, and experiment with temperature settings. But the most common reason a RAG system gives a wrong answer has nothing to do with the LLM; it is because the right document was never retrieved in the first place. At CodersArts AI, our Hybrid Search and Re-Ranking: From Retrieval to Reliable Answers course is designed to help learners understand why pure vector search breaks and how to fix it u

The Quiet Backbone of Reliable AI Systems: Understanding Chunking in RAG
When people talk about building AI systems today, the conversation usually revolves around: Which LLM to use How to write better prompts Which vector database is fastest Which framework to choose These are important decisions. But there’s a quieter layer in the stack that often gets overlooked — and yet, it has a disproportionate impact on system performance. That layer is chunking . What Is Chunking, Really? At a surface level, chunking is simple. You take a document and spl

Satellite Data Analysis using RAG: AI-Driven Insights for Remote Sensing and Mapping
Introduction Modern satellite constellations generate petabytes of multispectral, hyperspectral, SAR, and LiDAR data every day, far outpacing the capacity of traditional analysis methods. Remote sensing professionals must interpret this imagery against historical baselines, evolving scientific literature, environmental benchmarks, and mission-specific requirements simultaneously. Satellite Data Analysis Systems powered by Retrieval-Augmented Generation (RAG) address this by d

Build Your First SaaS Product While Learning Development
Here is a frustrating truth that most coding courses never tell you: you can finish a full curriculum, earn a certificate, and still feel completely lost when someone asks you to build a real product from scratch. The reason is simple. Learning to code and learning to build a product are two different skills — and the gap between them trips up thousands of developers every year. The students who close that gap fastest are the ones who learn by building something real, with st
